Blackmailing someone into sex even if you are married to them is still Rape.

If Sami can get away with shooting Alan after he raped her I don't see why Nicole can't be forgiven for thinking killing Victor was her only option.

Sami shooting Alan was not calculated was it? my memory is fuzzy on that. perhaps someone can correct on that. on the other hand, Nicole murdering Victor was premeditated. She planned the whole thing and even used a disturbed teenager to carry out the diabolic plan and it was cold blooded murder.
